This book was released on 2014 with total page 143 pages. Available in PDF, EPUB and Kindle. Book excerpt: Platinum electrocatalysts are important for a number of low and zero-emission energy technologies, including low temperature fuel cells. For reactions such as oxygen reduction at a fuel cell cathode, poor kinetics and harsh operating conditions (which lead to catalyst degradation) dictate the use of large volumes of Pt for efficient electrocatalysis. This need for a large quantity of Pt increases the cost of the fuel cell and makes the technology too expensive to compete with petroleum based energy alternatives typically used in automotive applications. Improving the effective utilization of Pt enables the same performance to be achieved with a smaller mass of Pt. A more effective use of Pt can be achieved through the use of alternative catalyst layer designs. The work presented in this thesis demonstrates three novel Pt catalyst layer designs with the aim of improving the effective utilization of Pt for electrocatalysis. These designs include pure Pt ordered porous electrodes (Pt-OP electrodes), supported Pt nanoparticle ordered porous electrodes (support@PtNP-OP electrodes) and nanobowl supported Pt NPs (support@PtNP nanobowls). These designs aim to enhance Pt utilization by improving: i) mass transport through the use of an open porous design; ii) Pt electrochemical stability via the use of stable materials throughout the electrocatalyst design and/or through support interactions; and iii) Pt catalytic activity via favorable interactions with support materials. The preparation of these new Pt electrocatalyst designs is presented through the use of sacrificial templates. The new materials were extensively characterized by electron microscopy, X-ray spectroscopy, and electrochemical methods. The alternative electrocatalyst designs demonstrated here provide new routes towards enhancing the utilization of Pt for electrocatalytic applications.

Download or read book Solid Electrolytes and Their Applications written by E. Subbarao and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 309 pages. Available in PDF, EPUB and Kindle. Book excerpt: Defect solid state has been an area of major scientific and technological interest for the last few decades, the resulting important applications sus taining this interest. Solid electrolytes represent one area of defect solid state. The early work on defect ionic crystals and, in particular, the classic results of Kiukkola and Wagner in 1957 on stabilized zirconia and doped thoria laid the foundation for a systematic study of solid electrolytes. In the same year, Ure reported on the ionic conductivity of calcium fluoride. Since then, intense worldwide research has advanced our understanding of the defect structure and electrical conductivity of oxygen ion conductors such as doped zirconia and thoria and of the fluorides. This paved the way for thermo dynamic and kinetic studies using these materials and for technological applications based on the oxygen ion conductors. In the last few years we have seen the emergence of two new classes of solid electrolytes of great signifi cance: the fJ-aluminas and the silver ion conductors. The significance of these discoveries is that now (i) solid electrolytes are available which at room temperature exhibit electrical conductivity comparable to that of liquid electrolytes, (ii) useful electrical conductivity values can be achieved over a wide range of temperature and ambient conditions, and (iii) a wide variety of ions are available as conducting species in solids. The stage is therefore set for a massive effort at developing applications.
